Problems solved by technology

[0002] At present, the commonly used blast furnace top distributor mainly adopts planetary gear transmission gearbox for mechanical decoupling, and transmits the rotation and tilting movements to the rotary mechanism and tilting mechanism respectively. As we all know, the planetary gear transmission structure is more complicated, so the price is also relatively expensive. ;Recently, some fabric distributors have begun to use electrical decoupling, through motor or hydraulic mode to cooperate with gear transmission, that is, to cancel the planetary differential gearbox, and use two motors to independently drive the rotary gear and the tilting gear, so that the structure of the entire fabric gear box can be obtained. Simplified; but because only the planetary gearbox mechanism is canceled, the problem of shaking of the lower part of the rotary cylinder and the stability of the entire rotary part are still not resolved
At the same time, due to the rotary motion of this mechanism, the cooling and nitrogen blanketing of the distributor are difficult, resulting in large water consumption and nitrogen consumption.
[0003] Recently, some swinging schemes have also appeared, but there are also problems of poor stability and inaccurate cloth positions

Embodiment 1

[0029] Such as figure 1 , 4 -5 shows the first bidirectional swing roof distributor with a hollow ring according to the present invention, mainly including a gear motor 1, a hollow ring 2, a gear motor 3, a bevel gear 4, a ring rack 5, and a bevel gear 6 , Chute drum 7 and shell 8. It is characterized by:

[0030] Such as figure 1 , 4 As shown, the shell 8 is cylindrical, and is vertically fixed on the top of the shaft furnace or the blast furnace; the gear motor 1 is fixedly supported on the outside of the shell 8, and the hollow ring 2 is a swimming ring-shaped ring cavity with a rectangular or elliptical cross-section. The hollow ring 2 is horizontally arranged in the casing 8; along the direction of the X-circle axis, one end of the hollow ring 2 is supported on the casing 8 through a bearing; It is docked with the output shaft of the gear motor 1 after passing through the reducer; thus, the hollow ring 2 can be driven to swing around the X-circle axis;

[0031] Such...

Embodiment 2

[0035] Such as figure 2 , 4 As shown in -5, embodiment 2 is an improvement to embodiment 1, which can greatly increase the stability.

[0036] and figure 1 Compared to, the difference is:

[0037] The shafts at both ends of the hollow ring 2 along the direction of the X-circle axis are supported by bearings and protrude from the housing 8; the shafts of the hollow ring 2 protruding from the housing 8 are each connected to a gear motor 1; the gear motors are located at both ends of the X-circle shaft ,Such as figure 2 The negative distribution shown on the central axis of the Y circle can also be distributed in the positive direction, or the positive and negative directions can be distributed separately. As a result, the front and rear rotation and swing of the hollow ring 2 are made more stable.

[0038]Simultaneously, another gear motor 3 is also provided along the direction of the X-circle axis. The outlet shaft extends into the hollow ring; the end of the outlet sha...

Embodiment 3

[0043] Such as image 3 , 5 As shown, embodiment 3 is an improvement to embodiment 1, and the gear motor 1 and gear motor 3 in embodiment 1 are replaced by the push rod driving mode, and the push rod power source can be a hydraulic cylinder, a pneumatic cylinder or It is electric drive. The output shaft of the push rod is connected through a power conversion mechanism to convert thrust into rotational power. This improvement can also be adopted for Embodiment 2, which is not shown in the figure again.

[0044] In addition, the present invention based on embodiments 1-3 can have many possible combinations and deformations. For example, only one gear motor 1 or gear motor 3 is added in embodiment 2, or only one gear in embodiment 1 or 2 Motor 1 or just change a gear motor 3 to push rod drive and so on. Designs similar to this combined deformation made according to conventional technical ideas all belong to the protection scope of the present invention.

[0045] No matter wh...

Abstract

The invention relates to a furnace top distributing device with a hollow ring and a distributing method thereof. By adopting a hollow ring structure capable of bi-directional swing, a sliding cylinder can rotate at any height and swing towards any direction and a plurality sets of meshing mechanisms with meshed bevel gears and racks are all integrated in the annular cavity of the hollow ring through the bi-directional swing of the hollowing ring and the siding cylinder as the hollowing ring can automatically swing and the sliding cylinder supported and connected in the hollow ring can also independently swing. The furnace top distributing device with the hollow ring and the distributing method disclosed by the invention have the advantages of greatly simplifying the complicated gear structure required by the traditional distributing device, saving the cost and improving the utilization rate of space.
